Thermal Storage Unit Using the Triple Point of Hydrogen
MetadataShow full item record
The French space agency (CNES) has co-funded a Research and Technology program and CEA/SBT has developed a 14 K thermal storage unit using the triple point of hydrogen. The development unit is able to store 10 J at 14 K. The unit has been tested at various peak loads in order to validate the energy stored and to measure the temperature stability. This thermal buffer could be used in a cryogenic space mission subject to variable heat loads. The design of the unit will be described and the thermal results will be presented.
